Maou no Ore ga Dorei Elf wo Yome ni Shitanda ga, Dou Medereba Ii?

With an aloof demeanor, intimidating appearance, and tremendous power, Zagan the mage is seen as an evil sorcerer and feared by all around him. As he goes about his daily routine of studying magic and punishing any ruffians he comes across, he accepts an invitation to a mysterious auction featuring various items of a late Archdemon.

There, he is surprised to find Nephelia, a white-haired elf slave, as the main prize of the auction. Mesmerized by her beauty, he instantly falls in love and spends a fortune purchasing her without a second thought. However, due to his awkward manners and social ineptitude, he finds it difficult to express his feelings for her.

As the eccentric duo embark on a new journey together, Zagan and Nephelia learn to be more earnest with each other, forming a relationship that gradually grows to be more romantic.
